You need more runtime than a standard internal battery gives you, but swapping the whole UPS unit is overkill and costs more than it should. The Centurion RT 1000VA Long Run model has a larger internal charger built in so you can hang an external battery cabinet off the back and stretch your backup window as far as the job requires. No batteries included — pair it with an external battery cab for the runtime you actually need. Same true online double conversion, same 0.9 power factor, same 98% ECO efficiency as the standard RT. Rack or tower, your call
